Mnajdra is a special place where people used to live a long time ago. It's on an island called Malta. Mnajdra has really old rocks that were built into different things like walls, rooms, and even temples. These rocks were put together very carefully with no glue or cement, just like a big puzzle!
People who lived in Mnajdra a long time ago made special drawings on the rocks that tell stories or show important things they believed in. They also built special rooms and temples where they could go to pray or have ceremonies.
Even though Mnajdra is very old and people don't live there anymore, it's still very special and important to people who want to learn about history and the way people used to live a long time ago.
